With the improvement of energy efficiency requirements and the increasing awareness of environmental protection, waste heat recovery technology in the industrial field has received more and more attention.
Especially in large energy-consuming enterprises such as thermal power plants, recycling waste heat through exhaust steam heat recovery condensers has become an important means to improve energy efficiency.
However, accurate measurement of condenser water level has always been a key challenge to ensure efficient and stable operation of the system. This article will introduce the application practice of guided wave radar level gauge in such environment.
As an efficient waste heat utilization equipment, the working principle of the condenser is to use the heat of exhaust steam to heat the passing condensed water to improve energy utilization.
However, the water level control of the condenser is very critical. If the water level is too high, it may lead to a decrease in efficiency and even cause equipment corrosion; if the water level is too low, it may cause cavitation and vibration of the water pump, affecting the normal operation of the equipment. Therefore, it is crucial to accurately monitor and control the condenser water level in real time.
In this demanding scenario, traditional level measurement technologies such as pressure, float or capacitive sensors often fail to meet the needs because they are susceptible to changes in temperature, pressure, density and sedimentation. The guided wave radar level gauge stands out for its high accuracy and strong environmental adaptability.
It measures liquid level by emitting microwave pulses and receiving reflected signals, and can maintain accurate measurements even under extreme temperature and pressure conditions or when the dielectric constant of the medium changes.
A thermal power company used a guided wave radar level meter to monitor the condenser water level when implementing a spent steam waste heat recovery project. Since the working environment temperature of the company’s condenser reaches hundreds of degrees Celsius and the pressure far exceeds normal pressure, the traditional liquid level measurement method encountered great challenges.
After installing the guided wave radar level gauge, it not only realizes real-time and accurate monitoring of water level, but also optimizes the operation strategy of the entire system through data analysis.
By introducing guided wave radar level gauges, the condenser water level monitoring of this thermal power company has become extremely simple and reliable.
The application of this technology not only improves the waste heat recovery efficiency and reduces maintenance costs, but also provides guarantee for the long-term stable operation of the equipment.
It is foreseeable that guided wave radar level gauges will play an increasingly important role in dealing with liquid level measurement problems in complex and harsh industrial environments.
